Issue/Introduction

Is there a way to check what space is actually being used/what is still available? Plan on adding additional global vars and ssm tables, and don't want to run out of space. Thanks in advance.

Environment

Release : 14.0

Component : OPS/MVS

Resolution

So for the current SYSCHK1 dataset, to know how it is doing in regards to the variables, etc take a look at the following parameters in the OPS/MVS Parms screen (=4.1.1)

GLOBALUSED          2471                NUMBER OF GLOBAL VARIABLES IN USE    
GLOBALBLOCKSUSED    5030                NUMBER OF GLOBAL VARIABLE BLOCKS IN U
GLOBALFREEAREAS     81                  NUMBER OF FREE AREAS IN GLOBAL WORKSP
GLOBALFREE          16398               NUMBER OF FREE GLOBAL VARIABLE BLOCKS
GLOBALALLOC         21428               NUMBER OF ALLOCATED GLOBAL VARIABLE B
GLOBALMAX           30000               MAX NUMBER OF GLOBAL BLOCKS          

The GLOBALMAX is what will fit as defined today, and GLOBALALLOC is the highwater mark.  Depending on what needs to be added, use the DASD Calculation Charts in the Installing Guide to determine space needed.  However, a simpler, unofficial method would be to note the current GLOBAL* variable values, add a variable, etc and see how much the values change.   This would give an indication as to whether more space needs to be allocated or not.
